Putting this here as it helped me out so I figure others might find it helpful.
Have you got frustrated with lighting illuminating everything when you want to light up just the character or just the map? (I'm looking at you Volumetric lighting). Well turns out that what gets lit up can be fully controlled through graphicsmod.
Go to settings tab and at the bottom activate the "Show Advanced Settings" box.
This gives you a bunch more controls in the Lights tab as seen in this image.
Now take a look at what happens. I've activated a Volumetric Char Spot light on the character. As you can see, the light doesn't just illuminate the char, it lights up behind and around her as well which kind of defeats the point of using a char spot vs a regular spot. Well this is where the advanced menu comes into play. I've highlighted the MAP button. This is with it active and illuminating the map.
And here is the same but the MAP button deactivated.
As you can see, the lighting only illuminates the character as intended, leaving everything else alone.
Hope someone else found this helpful. This had been bothering me for a while since i like using volumetric lighting more than the vanilla stuff but got stuck when I just wanted char lighting.
I learned about this from a lighting tutorial
